Scientists at the University of New South Wales (UNSW), Australia, are developing a novel way to store hydrogen that could help turn it into a viable portable fuel source. The research centers on using synthesized nanoparticles of the compound sodium borohydride (NaBH4 for those who love chemistry), which when encased inside nickel shells exhibits surprising and practical storage properties including the ability to reabsorb hydrogen and release it at much lower temperatures than previously observed, making it an attractive proposition for transport applications.
